SHEET-DELIVERY APPARATUS FOR PRINTING-MACHINES.

SPECIFICATION forming pa'rt of Letters Patent No. 374,465, dated December 6, 1887.

Application filed June 24,1986. 'Renewed October 15, 1887. Serial No. 252,485. (No model.)

To all whom, it may concern,.-

Be it known that I, GEORGE I2. FENNER, a citizen of the UnitedStates, residing at New London, in the county of New London and State of Connecticut, have invented new and useful Improvements iu Sheet-Delivery Apparatus for Printing-Machines, ot' which the following is a specification.

My invention relates to improvements in sheet-delivery apparatus adapted more especially for printing-presses, and has for its object to provide novel and efficient mechanism for taking the sheets from the impression-cylinder and depositing them properly on a suitable table or support. This object I accomplish in the manner and by the means hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure l is a side elevation of a printingpress containing my invention. Fig. 2 is au end elevation of the same, partly in section. Fig. 3 is a detail view of an impression-cylinder and carrying-reel.

Similar letters indicate corresponding parts.

The letter A designates a suitable supporting-frame.

B is an impressioir-cylinder, and C is a typebed, both placed in proper relation to one auother.

D is a driving-shaft, which, by means of gearwheels D' D2, transmits motion t0 the main shaft E. The shaft E, by means of a crank, E', and rod E2, imparts motion to the traveling rack-wheel E3, which meshes into a stationary rack, Et, Fig. 2. The rack-wheel E3 engages with a suitable rack, E5, attached to the type-bed C, and imparts a reciprocating motion to the type-bed. A rack, C', on the type-bed is suitably arranged to engage with a cog-wheel, B', of the impression-cylinder B and to impart motion t0 the said cylinder B. In the case of stop-cylinder presses a portion of this cog-wheel B' is out away, so as to permit the type-bed C to travel while the cylinder is at rest during certain intervals.

The cog-wheel B' is indicated in Fig. l, chiefly by dotted outlines.

The impression-cylinder is provided with a catch or lug, F, which is adapted to be engaged by a catch-lever, F', which operatesto check, hold, and start the impression-cylinder B in any well-known manner. In the eX- ample shown in the drawings the catch-lever F is properly pivoted or fulcrumed, as at f, and is vibrated or moved by a cam, F2, and a rod, F3. The rod F3 is connected atene point to the lever F', and said rod F3 has a rollerstud,j", or other suitable appliance for engaging in a suitable way the cam F2. the rod F2 is slotted or bifurcated, so as to clear the main shaft E, and is provided with a block, f2. Y

The impression-cylinder is provided with suitable grippers, B2, for holding the sheet to be printed upon the cylinder. The grippers B2 are operated by springs and by cams or posts B.3 B2 suitably arranged in any wellknown manner.

G G are` racks secured to the frame A, and said racks G G are engaged by gear-wheels I I, which gears, with their shaft I', support a carrier-reel, J J, which is constructed to receive the printed sheet from the impressioncylinder B. The gear-wheels I I are adapted to engage at proper intervals with a revolving support, K, which in the example shown in the drawings is a gear-wheel which receives motion from the impression-cylinder Bth rough the gear K. The gear-wheels I I andthe carrier-reel J thus receive a rotary motion. The carrier-reel J, as seen in the drawings, is formed of two disks. By making said disks adj ust-able toward or from one another on the shaft I, said carrier-reel J can be adj usted for varying width of sheets.

To the main shaft E is secured a suitable cam, I2,which engages with a roller-stud, I, on a lever, I4. The lever Ii is properly fulcrumed or pivoted, as at ii, and said lever I connects by a link, I5, with the shaft I', carrying the gearsI I. A rod, IG, extends through a socket, 126, on the frame of the press and is connected to the lever I4. The rod, IG, has a collar, ik, which is subjected to the action of a spring,l2, in such a manner that the roller-stud I of the lever I* is continuallyl kept in engagement with the cam I2. Other known means may, however, be employed to keep the roller-stud I3 in engagement with the cam I2.

The gear-wheels I I have bearings for a gripper-shaft, M', on which shaft are mounted grippers M. The grippers M are operated by a lever, M2, fulcrumed on one of the gear- Part of 6o TOO wheels I and subjected to the action of a spring in any well-known manner.

Trip-cams M3 M4, suitably fixed to the device, operate the lever M2 and grippers Mat proper intervals. The grppers M impinge upon a suitable rod or blade, K", properly attached tothe gear-wheels I, so that the edge of a sheet can be held between the grppers M and the blade Kt.

Instead of a rod, K, a radial web or partition can be employed extending from the shaft I toward the circumferenccs of the gearwheels I. To allow room for such a partition the disks, which in this case form the reel J,

will have to be slotted.

When a sheet is to be delivered from the im pressioncylinder B tothe carrier-reel J ,the carrier-reel is moved by the cam I2 and lever I4 toward the cylinder I3. The gears I of the carrier-reel pass onto the rotating support K,

as seen in Fig. l, and the reel J is now caused to rotate by the rotation of the gear K2 on the cylinder B. The grippers M of the carrier reel J grasp the sheet on the impression-cylinder when an edge of said sheet has been passed within reach of said grippers M, and said sheet is thus taken off the cylinder B and wound onto the reel J. The reel J is then, by the action ot' the lever I", moved in the direction of arrow 3, or away from'the cylinder B and along the racks G. During this movement of the reel J the grippers M are actuated at the proper time by the cam or post M, so as to release the sheet which detaches itself from the reel J, and asvthe reel J passes on in the direction of arrow 3 the sheet from the reel J comes to rest upon a table, H.

By having the reel Jand cylinder B ofproper respective size the circumference ofthe reel J when taking a sheet from the cylinder will be in contact with the circumference ofthe cylinder B, so thatsaid sheet cannot bend or sag during its passage from the cylinder B onto the reel J. In Figs. 1 and 3 the cylinder B and reel J are shown in contact. As seenin Fig. 1, the reel J, whenin contact with the cylinder B, receives motion from two sources, one beingthe engagement of the gear-,I of the reel with the gear K2 of the impression-ey'linder, and another being the engagement of the gear I with the rotating support K, which support in its turn receives motion through the gear K from the gear K2 of the impressioncylinder. that one of these sources of motion can be dispensed with without preventing the operation ofthe device. rlhus, for example, the gear K can be dispensed with, and as the gear I is ren i volved by the gear Kl the rotating support K receives motion from the gear I. In this lastnamed case the support K, instead of being in the shape of gear-wheels, may bein the form of plain rollers or disks; or the gear I may beso arranged as not to come into engagement with the gear K2, in which case the gear K2 imparts motion through the gear K to the gear K,

It will of course b e readily'noticed from which gear K the gear I and reel J receive motion when the gear I is in engagement with the rotating support K.

The gear K and the rotating support K can be suitably mounted in the frame A. The reel J, instead of consisting of two disks, may be in the form of a roller; but by having only disks which are arranged so as to come into contact with the edges of a sheet, smutting of the sheet is avoided. In the case of a stopcylinder press the reel-support K, if it receives motion from the impression-cylinder, will have an intermittent rotarymotion. If the rotating support receives motion from the gear vI, said support will rotate only during those intervals that the gear I is rotated by the gear K2 of the impressioncylinder, irrespective of whether the impression-cylinder rotates continuously or intermittently. The support K, as is seen, is stationary or mounted on an axle having stationary bearings.

What I claim as new, and desire to secure by Letters Patent, is- A l. The combination, with the impression4 cylinder, ofthe carrier-reel J, having a shaft, I, provided with a gear, I, the rack G, means, substantially as described, for moving the gear on the rack to and from the cylinder, and a rotating wheel, K, mounted in stationary bearings supporting the reel-shaft gear and located between the rack and the.impression-cylinder.

2. The combination, with the impressioncylinder,of a carrier-rcel movable in a right line to and from the cylinder, a rotating reel- Supporting wheel, K, mounted in stationary bearings, and means, substantially such as de-V scribed, for moving the carrier-reel to and from the cylinder and intermittently into and out of engagement with the rotating supporting-wheel.

3. The combination, with the impression cylinder and the gear K2 thereof, of the carrier-reel J, having a gear, I, adapted to engage with the gear on the impressioncylinder,

and a rotating support for the carrier-reel mounted upon an axle the bearings of which are stationary, substantially as set forth.
